About B2364

B2364 is a generic (obd-ii standard) body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B2364 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

Because B2364 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The body control module monitors the fuel filler door circuit, which can include either an electric solenoid or motor that releases the door lock when commanded, or a position switch that indicates whether the door is open or closed. DTC B2364 sets when the body control module detects an open circuit on the fuel filler door circuit, meaning either the solenoid drive output cannot sense load current when commanded active, or the door position switch input shows no continuity in either state. The circuit is normally a low side or high side drive output for a release solenoid or a pulled up logic...
